AS1163 C250

AS1163 C250 is a steel grade of hollow section steels specified in the AS/NZS 1163 standard. And, AS/NZS 1163 is the Australian and New Zealand standard for cold-formed structural steel hollow sections. These sections are normally electric resistance welded and are used for structural purposes and engineering applications. There are three main steel grades specified, with or without impact properties, which vary in yield strength and tensile strength. It is important to note that the standard applies to both welded and seamless hollow sections in circular, square, and rectangular shapes. The AS/NZS 1163 standard is an important tool for engineers when specifying the required properties of cold-formed structural steel hollow sections.

How do distinguish AS1163 C250 from other steel grades? The nominal minimum yield strength of hollow sections is used to determine the grade classification (in MPa). The prefix “C” is used before the value of the nominal yield strength of the steel to indicate that the section is cold-formed. Only cold-formed structural steel hollow sections are covered by AS/NZS 1163. Also, if the number is followed by a suffix “L0”, this steel grade must meet the impact test requirements. As a result, AS1163 C250 means cold-formed structural steel hollow sections with 250 MPa minimum yield strength, and no impact test required.

Chemical Composition of AS1163 C250 Pipes

Sampling from AS1163 C250 materials for chemical analysis is a vital step in ensuring the accuracy of the results. The method of sampling shall be in accordance with AS/NZS 1050.1 or ISO 14284, and the composition shall be determined in accordance with AS/NZS 1050 series Standards or other procedures that achieve the same, or better, degree of accuracy. This ensures that the results are accurate and reliable. Chemical analysis is an important tool for many industries, and it is essential that the results are as accurate as possible. By following the correct sampling procedures, we can ensure that the results are reliable and informative.

Mechanical Properties of AS1163 C250 Materials

When it comes to understanding the strength and durability of AS1163 C250 materials, there are three key tests that engineers rely on: the tensile test, the impact test, and the flattening test. The tensile test measures a material’s ability to withstand forces that try to pull it apart, such as the stresses that occur during welding. The impact test assesses a material’s resistance to shattering forces, such as those that can occur during a car crash. And the flattening test gauges a material’s ability to resist crushing forces, such as those that might be exerted by heavy machinery. By understanding the results of these tests, engineers can ensure that AS/NZS 1163 C250 materials will be able to stand up to the rigors of their intended applications.

The tolerances of AS1163 C250 Standard

The tables given below show the dimensional and mass tolerances for AS1163 C250 cold-formed hollow sections. The first table is for shape and mass, while the second is for length. As can be seen, the tolerances are relatively tight, especially for mass. This is due to the fact that hollow sections are often used in load-bearing applications, and even small deviations from the nominal dimensions can lead to significant changes in performance. As a result, it is important to ensure that cold-formed hollow sections meet the tolerances given in the tables below. Doing so will help to ensure that they perform as intended and do not fail prematurely.

AS/NZS 1163 C250 AND API 5L Gr. B Dual Specs Pipes

There is a high demand for dual-spec pipes, such as AS1163 C250 / API 5L Gr. B materials. To demonstrate conformity with these materials requirements, we conduct a number of mechanical/chemical tests. To ensure compliance with tensile and fracture toughness requirements, API 5L and AS/NZS 1163 each need separate test methodologies. To establish structural and pressure integrity, hydrostatic pressure tests and non-destructive weld inspection are also done.
